The A2UI client capabilities this renderer supports — the typed
`a2uiClientCapabilities` metadata a host attaches to agent requests so
the agent knows which component catalogs it may target
(catalog negotiation, A2UI v0.9 transport metadata).

```typescript
export declare function a2uiClientCapabilities(): A2uiClientCapabilities;
```

```ts
const metadata = { a2uiClientCapabilities: a2uiClientCapabilities() };
```
